Supported Boot Paths

SCSI devices are bootable when connected to the FWSCSI port on the System card.
Diskless workstations can only boot from the LAN port on the System card.

ISL Environment

The ISL environment provides the means to load the operating system (HP-UX) en-
vironment. The ISL environment also provides an offline platform to execute diag-
nostic and utility programs from a boot device when HP-UX does not load.
The ISL program is the first program loaded into main memory from an external
media (LAN, disk, or tape) and launched by the initial program loader (IPL) routine
during the Boot Administration environment.
The ISL environment provides the following capabilities:
D
Execute user-entered commands to modify boot device paths and boot op-
tions in stable storage.
D
Run off-line diagnostic programs (TDIAG, IOMAP).
D
Provide automatic booting of the HP-UX O/S after power-on or reset.
The ISL program provides a standalone environment for loading offline diagnostic
and utility programs from the LIF directory. The ISL program also provides user
commands to configure the boot parameters into Stable Storage.
